Determining storage space required

Before you schedule a time to install this release, determine the available storage space and the storage space that is required.

Load-source disk unit requirements

To upgrade to the V5R4 Licensed Internal Code, you must have a load-source disk unit of 17 GB or larger for each server or logical partition.
The procedures in this topic might not include all requirements for storage that you have on your server. If you are preparing to upgrade or replace software using an image catalog, ensure that you have reviewed the topic, Determining storage requirements for image catalog installation.

To determine if you have enough storage space for the new release, perform the following steps:

Type GO LICPGM. The Work with Licensed Programs display appears.
Choose option 5 (Prepare for Install).
Type 1 next to Estimated storage requirements for system ASP. The Estimated Storage Requirements for System ASP display appears.
Enter the total storage that is needed for additional applications. Include storage for single licensed programs that were not included on your customized installation list, and storage for Programming Request for Price Quotations (PRPQs), licensed program offerings (LPOs), or third-party software.

Round up to the nearest whole number. Refer to the product documentation to determine how much additional storage is required. The system uses this number to calculate the disk storage that is required to install the target release.

Include third-party software only when you intend to store it in the system ASP. Refer to the Backup and Recovery manual or Backup and recovery for more information about system ASPs.
Press Enter to continue to the next display. The second Estimated Storage Requirements for System ASP display appears.
This display shows you information that you will need to determine whether enough disk storage is available to complete the installation.
Compare the value for Storage required to install target release with the value for Current supported system capacity. If the value for Current supported system capacity is greater than the value for Storage required to install target release, you can continue with the installation process. If the system capacity is less than the storage required, you might need to add additional disk units or install fewer optional programs.
Press Enter to return to the Prepare for Install display.

Repeat this process whenever you make any changes to your system that affect the available disk storage space.
